Sam's wife, Michelle aka "Quinn", was back and forced undercover again in "Wanted." It was inevitable that Isaak Sidorov would eventually return and insist that Quinn complete the assassination of Anatoli Kirkin. That day arrived and provided NCIS with an opportunity to find out where Sidorov was keeping the three stolen nukes.
Of course, Sam wasn't thrilled to see Michelle back at work and putting herself at risk. I have mixed feelings about this. I understand that Sam wants to protect his wife, but at the same time he feels it's okay for him to put his life on the line every day. It's definitely a double standard, but one that at least makes sense. There is a difference between one parent risking their life and both parents doing it. And, they decided that Michelle would be the one to give up the job.
Love will make people do crazy things and for Sam that meant breaking out of jail. He had to be there to protect his wife. It wasn't that she couldn't take care of herself, but he felt a duty to be there there for her. And, in the end, that was a good thing.
